This invention relates to a method for producing doll heads and similar articles, and to means for performing said method.

An object of the invention is to provide a method by which doll heads and similar articles mayy be rapidly produced and by whichthe heads produced will be of great accuracy in their various details Vas to form.

A. more detailed object is to provide an l0 improved method whereby the two halves or sections of` a doll head may be joined to make up a complete head.

A further object is to provideY a tool by which to carry out this improved method.

moulding tool within which the doll head, that is one of the halves or sections of the head, may be moulded under heavy pressure and subject to desired heat conditions,v

and by part of which the moulded head section may be temporarily supported after the remainder of the mould is removed.

A further object is to provide a mould having an intermediate part or member constructed to serve as a temporary carrier for the moulded product during and following the separation of the two opposite parts or members of the mould, whereby to facilitate the convenient removal and discharge of theV product from the mould.

A further detailed object is to provide a mould for forming doll heads and having a separately formed and readily interchangeable section including the part for forming the two eye sockets and immediately adjacent parts of the doll head.

Other objects and aims of thel invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations,.

arrangements of parts and applications of principles constituting the invention; and

the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of this specication, and in which I have shown merely a preferred form of embodiment of the invention A further detailed object is to provide av 192e'. seria; No. 120.347.

Fig.'l is averticalsectional view through a mould constructed in yaccordance Withfthisi invention, the parts of the mould being shown in their nested relation with a doll being shown in a separated 'co-ndition.-

' Fig. 3 is a vertical sectional view taken transverse to the plane of the section Fig, l.

Fig. 4 is a bottom plan view of the upper part or member of the mould. v

Fig. 5 is a transverse sectional view through the front and rear sections of a doll head, the front section being the product of the mould herein illustrated andv the rear` section being the product of `a mould similar to that herein illustrated except that whereas the present mould embodiesy parts having a surface contour corresponding to the contour desired for the face portion ofthe doll head, the second mould hasV parts corresponding to the contour desired for the back portion of the doll head.

Referring to the drawings for describingin detail the method and structure therein illustrated the reference character L indicates-the to'p part or member'of' the mould, the reference character G the bottom part or memberV of the mould and the reference vcharacter H the intermediate mould. c Y v Each of theseV Vmembers isv preferably formed as a hollow metallic casting, the interiors thereof as 1,2 and 3 respectively vbeing adapted to contain a. heating fluidsuchas steam, hot water, or other suitable medium supplied thereto through feed pipes 4, '5 and 6 respectively, it being-understood that these pipes communicate with any appropriate source ofthe heating medium and are made suitably flexible to permit independent movement ofthe members L, H and G during the opening andthe closing of the mould.

The top and bottom members L and G are furnished withy the usual dowel seats 7 7 and part vor member of the,

the intermediate member H carries opposite- Y this opening, below the plane of the line indiy cated by the reference character 11 in Fig., 1 as at 12, corresponds to the contour desired for side and top portions of the exterior surface of the doll head, it being noted that this surface portion ofthe walls of said opening is given only a very slight taper or draft as compared to the taper or draft present in the depression 9, as at 13, and that this difference is intended to permit the bottom member G of the mould to draw readily away from the moulded product, or doll head section 14,

without likelihood of separating the product from the intermediate member H, as will be further on herein referred to.

Above the plane of the line 11 the side walls of the opening 10, as at 15, are substantially vertical and smooth, i

The upper member L is provided with an extension 16 projecting downwardly the-refrom through the opening 10 and into the depression 9 said extension constituting the core part of the mould. Below the plane of.

line 11 the surface of this extension or core part is of the size and contour desired for the A interior surface of the doll head section and is modelled so as to provide ample draft to permit its ready removal upwardly in operation.

Above the plane of the line 11 the side walls of the extension, as at 17, are substantially straight and smooth and of a size and contourl to slide as a sort of piston snugly within the straight smooth portion 15 of the opening in theintermedia'te member H.

Intermediatelybelowk the' plane of line 11.V

the wall surface of theextension is stepped inwardly so as to provide a ledgeas'lS disposed to form a corresponding margin al recess 19 at the upper or rear edge of the product 14 as will be readily understood.

In use, the three members of the mould are separated to or beyond the extent as seen in Fig. 2. A suitable quantity of mouldable material is placed within the depression 9 of the bottom member H after which the three members of the mould are brought together in suitably .timed relation to each other so that the mould members will finally occupy the position as seen in Fig. 1 with the mouldable material fllling'the space between the mould members to thereby constitute the doll head,

or product, 14, the final movement in bringing the mould members together being a sllding movement of the piston portion 17 downwardly along the portion 15 of the opening 10 thereby conning the mouldable material. The pressure employed is preferably very heavy so that the mouldable material is greatly condensed and solidified and made to accurately conform to every feature of contour of the mating mould surfaces.

During the time while the mould members are compressing the material being moulded the mould members are maintained suitably heated by the fluid within the cavities 1, 2 and 3 so that the material being moulded is at the same time being subjected to an appropriate Vdegree of heat serving to further and more completely and quickly solidify the material preparatory to the separation of the mould members. Y

In separating the mould members the upper and4 bottom members L and G may be loosened and moved simultaneously if desired but itis preferable that the upper member L and the intermediate member H shall remain undisturbed while the bottom member is being loosened and relatively lowered away since by this means the moulded material product, or doll head, is held by its upper marginal portion in a vise-like grip between the opposing walls of the mould members L and H during the period of separation of' the bottom member. Little or n likelihood is thereby permitted of the product following the bottom member.

After the bottom member has been loosened then the upper member maybe loosened and lifted away leaving the product suspended by its upper marginal portion within the opening 10 of theV intermediate mould member. Owing to the incline or draft of the walls of the opening 10 below the plane of line 11 no possibility exists of the product following the upper member.

lVith the bottom member G and the upper member Lrseparated Afrom the intermediate member thek product may be thereafter readily removed by hander otherwise from its connection with the intermediate member. A slight downward tap against the product is ordinarily sufficient. Y

lNhile I have hereinabove referred to the taper or draft provided within the opening 10 of the intermediate member as being very slight, it will be understood that this relatively slight draft need not be uniform throughout the circumference of the opening. At some point, as for instance at the ear portions of the doll head, indio-ated by the reference characters 20-20 in F ig. 3, the draft is quite pronounced tov thereby giveappropriate prominence to said ear portions, while at other points the draft may be practically nil. The essential requirement in this( connection is simply that the draft shall be' lfollowing the opening of the mould the intermediate mould section also provides for a line of separat-ion as at 2l of the mould members in the region or plane of the doll head ears without requiring a corresponding line of separation between the front and bach sections of the finished doll head. A. more accurate and life-like moulding of the ear portions of the doll head is thus rendered possible and at the same time the upper or rear edge of the product is maintained on a single dat plane which is of smooth and regular curvature as clearly seen by reference to the part lSin Fig'. 5 instead of being of irregular contour following the outline of the ears as has been heretofore customary in the ina-king its forward edge portion, as at so,

A Al owing to the of two-part doll heads.

The back section as 22 of the doll head has f' shaped to mate with the shape of the rear edge of the front section, as clearly indicated in Fig. G., the two parts interfitting and telescoping one into the other. @fr suitable adhesive is employed to hold the parts together. The joint is uniform and accurate throughout, and overlapping engagement of the parts very little if any operation is required to complete. the outside surface. Itis intended in fact thatthe pressure ei;- erted for forming the cast product shall be suciently great so that the surface of the product shall be ready for immediate tinting and finishing without preliminary filling and smoothing with heavy putty and paint as has been heretofore the practice.

At the proper location in the upper mould member L there is provided a recess 24 into which is fitted a separately formed member 2o having its under edge or surface portion 26 shaped to form the interior contour of the doll head at and between the eye-sockets, said nirface 26 including a pair of eye-socket forming parts 27-27. rlhis member 25 is made separate from the remainder of the mould in order to facilitate the more accurate shaping of its surface portion 26 and the eyesocket forming parts 27-2'?, well as to facilitate its interchange with other menif bers having slightly differing surface formation as may be required for the manufacture of doll heads having` different facial characteristics or as may be required for the mounting of eye sets of different constructions.

The eye-socket forming parts 27-27 each have a central opening as 28 therethrough into which projects a lug as 29 carried by the bottom mould member vH thus insuring perfect alignment of the parts.

A suitable opening as 30 is provided through the member L through ywhicha bolt or the like as 3l may extend by which to hold the member 25 in position. Y

The member 25, and its bolt 3l, are preferably formed hollow in order to permit of a circulation of air or other cooling medium into position adjacent the eye-socket forming parts 27 *27, this being desirable in some instancesto prevent excessive heating of the relatively thin walls for the cast product in the region of the eye openings thereof.

As many changes could be made in this constructionwithout departing from' the scope of the invention as delined in the following claims, it is intended thatall matter contained in the above description yor` shown in the accompanying drawings, sha-ll be interpreted as illustrative only and not in a limiting sense. v

Having thus described my invention, what I'claim as new and ydesire to secure by Letters Patent is l l. The herein described method of producing moulded doll heads having eye openings therethrough, which method consists in providing suitable mould members, placing a quantity of mouldable-material between said4 mould memberswhile said mould members are separated, forcing` said mould members together to thereby mould the mouldable material, applying heat to said mould members to heat the mouldable material and meanwhile applying 'a cooling medium to a part of the mould adjacent said eye openings.
